The site\u2019s complex terrain required an accurate geological survey of the rock mass foundation types and structural plane upon which the dam design would be based.<\/p>\n<p>A curved ecological fishway that enables migrating fish to pass through the dam demanded significant excavation that necessitated more than traditional 2D processes. Designing the rockfill dam section involved many control conditions and complicated interactions with the landscape, which cannot be solved with conventional 3D modelling.<\/p>\n<p>Additionally, multidiscipline engineering and visualisation capabilities were essential to design the metal structure, hydraulic machinery and engineering, and an electromechanical system. Therefore, Liaoning Water realised that it had to adopt Building Information Modelling (BIM) solutions to overcome traditional design limitations on this large-scale water conservancy project.<\/p>\n<h3>BIM applications overcome traditional design restrictions<\/h3>\n<figure id=\"attachment_111336\" aria-describedby=\"caption-attachment-111336\" style=\"width: 638px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-111336 \" src=\"https:\/\/www.pbctoday.co.uk\/news\/wp-content\/uploads\/2022\/05\/2382-LSD-34-RESIZED-300x169.jpg\" alt=\"severe flood risk\" width=\"638\" height=\"359\" srcset=\"https:\/\/www.pbctoday.co.uk\/news\/wp-content\/uploads\/2022\/05\/2382-LSD-34-RESIZED-300x169.jpg 300w, https:\/\/www.pbctoday.co.uk\/news\/wp-content\/uploads\/2022\/05\/2382-LSD-34-RESIZED-768x432.jpg 768w, https:\/\/www.pbctoday.co.uk\/news\/wp-content\/uploads\/2022\/05\/2382-LSD-34-RESIZED-696x392.jpg 696w, https:\/\/www.pbctoday.co.uk\/news\/wp-content\/uploads\/2022\/05\/2382-LSD-34-RESIZED-747x420.jpg 747w, https:\/\/www.pbctoday.co.uk\/news\/wp-content\/uploads\/2022\/05\/2382-LSD-34-RESIZED.jpg 800w\" sizes=\"auto, (max-width: 638px) 100vw, 638px\" \/><figcaption id=\"caption-attachment-111336\" class=\"wp-caption-text\">Design efficiency increased by 40% to deliver the engineering design two weeks ahead of schedule<br \/>Image: \u00a9 Liaoning Water Conservancy &amp; Hydropower Survey &amp; Design Research Institute<\/figcaption><\/figure>\n<p>After considering their options, the team employed Bentley\u2019s BIM software for accurate 3D design. Liaoning Water integrated <a href=\"https:\/\/www.pbctoday.co.uk\/news\/bim-news\/legion-simulator-and-openbuildings\/77321\/\" target=\"_blank\" rel=\"noopener noreferrer\">OpenBuildings<\/a> and OpenRoads Designer to streamline collaboration among multiple engineering disciplines and manage data.<\/p>\n<p>They surveyed the landscape and created a detailed 3D geological model to precisely calculate excavation volumes and plan excavation processes. This visualisation in OpenRoads also allowed the project team to accurately position the ecological fishway and connect the structure\u2019s complicated spatial curve to the landscape.<\/p>\n<p>The rockfill dam section was designed using OpenRoads\u2019 linear engineering capabilities to generate a truthful 3D model incorporating all control and boundary conditions. Several engineering disciplines collaborated on the design of the concrete dam in OpenBuildings, allowing the hydraulic machinery, metal structure and electromechanical equipment to be designed to avoid collisions.<\/p>\n<h3>Leveraging BIM technology to deliver a digital twin<\/h3>\n<p>Liaoning Water reduced design error by 90%. Delivering a technologically advanced model minimised changes to the overall design during construction. Accurately calculating project cost in the design stage of the project decreased the government\u2019s overall investment.<\/p>\n<p>With the support of open modelling technology, the project team improved design efficiency by 40% to deliver the plans two weeks ahead of schedule. They leveraged BIM software to produce a <a href=\"https:\/\/www.pbctoday.co.uk\/news\/bim-news\/telecoms-digital-twin-solution\/90931\/\" target=\"_blank\" rel=\"noopener noreferrer\">digital twin<\/a> that provides full lifecycle support of the dam, including management during construction, operations and maintenance.<\/p>\n<p>Using this project as the foundation for BIM usage on future water conservancy projects, Liaoning Water has implemented corporate 3D collaborative design standards and trained personnel to become a regional leader in BIM application.<\/p>\n<p>&nbsp;<\/p>\n<p><a
